That depends on what "scanned data" menas....
There are twos scenatios wich wie have both in use...
1.) Scanner is directy connected to the frontend and does a "Keyboard input".
In this case you can build a dynpro like this:
SCANNED DATA _______________________________
where Scanfield is an input field in with the scanner "wirtes" it's data and
Scanned data is i.e. a table-control where the scanned data is shown.
The scanner should do an AUTO-ENTER. So the SAP-Transaction could
start executing after every scanning and cummulate the data into an
The cumulated data is being processed by pressing SAVE on the GUI-Dynpro.
2.) The scanner is "batch type" and puts it's data to a file or database
If the data is put to a database you'll first need to export them to a file.
If the scanner writes to a file this is not neccesary !
Then write a batch programm that imports that file (using GUI_UPLOAD)
and does the processing.
In both cases the interpreation of that what's being scanned is a matter of the SAP-transaction the does the processing.
Hope that helped a bit...
Some points would be nice...
